ARC GFRP Rebar

ARC is the largest GFRP rebar manufacturer in India, with 12 years of experience in the industry. We operate 14 machines for straight GFRP rebars and 4 machines for GFRP bend rebars, with a monthly production capacity of 700 tons. ARC boasts comprehensive in-house testing facilities adhering to ACI-440.1R-15 and BIS 18256-2023 standards. Currently, ARC offers GFRP straight bars in diameters ranging from 4mm to 50mm and bent stirrups from 6mm to 25mm.

GFRP rebar stands for Glass Fiber Reinforced Polymer rebar. It is a type of reinforcing bar used in concrete structures as an alternative to traditional steel rebar. GFRP rebar is made of glass fibers embedded in a polymer resin matrix, typically vinyl ester or polyester resins. The glass fibers provide tensile strength, while the polymer resin binds the fibers together.

GFRP (Glass Fiber Reinforced Polymer) rebars are manufactured using an extrusion process, which can produce both straight and bent rebars. The manufacturing process involves two distinct forms, each tailored to meet specific requirements.

  • Straight GFRP Rebars: Made by extruding a mix of glass fibers and thermoset resins through a heated die, producing solid, cured rebars ready for cutting and packaging.
  • Bent GFRP Rebars: Similar extrusion process but the material remains partially cured, allowing it to be bent into various shapes like hooks or stirrups before full curing.

Once the desired bend shape is achieved, the partially cured GFRP rebar is subjected to a controlled heating process, typically in an oven or a heated molding setup. This post-bending heat treatment fully cures and solidifies the polymer matrix, locking in the desired shape and ensuring the rebar’s structural integrity.

      GFRP Bend Rebars:

      The manufacturing of bent GFRP rebars follows a similar extrusion process, but with a critical difference in the curing stage. Instead of fully solidifying the extruded material, the GFRP is maintained in a partially cured or “green” state, allowing it to retain sufficient pliability for subsequent bending operations. This semi-solid state enables the GFRP rebar to be formed into various shapes and configurations, such as hooks, stirrups, or custom-designed geometries, as per project requirements.

      As GFRP Rebars are brittle rigid material (Ductibility Low) and break at the ultimate point, it can’t be bend at site like steel. So, the bend bar can be factory made according to our manufacturing process with client specifications, design & drawing.
